La prensa mística como redención de las almas del Purgatorio. A propósito del lienzo de la Iglesia de San Francisco de Córdoba

La cordobesa parroquia de San Francisco cuenta entre su patrimonio artístico con un monumental lienzo que ha sido objeto de numerosas referencias en la historiografía artística, si bien todas ellas lo han hecho de manera meramente descriptiva o aludiendo tangencialmente por su «rareza» iconográfica y su carácter singular, por lo que hasta hace relativamente poco tiempo no ha habido acuerdo en señalar su temática y a qué finalidad obedece, para así adscribirlo a un determinado corpus iconográfico: nos referimos al cuadro que representa la Prensa Mística. Con esta contribución lo que se pretende es delatar cómo a través de la obra estudiada se han utilizado pedagógicamente dos de los instrumentos fundamentales por los que la Iglesia postridentina transmite determinada ideología: la existencia del Purgatorio y el culto al Santísimo Sacramento.As part of the patrimony of the San Francisco’s church in Cordoba there is a monumental canvas which has been subject of several references in the artistic historiography even though all of them have only merely been descriptive or mentioning it just because of its iconographic rarity and its odd character. That is probably the reason why only until very recently has not been an agreement in pointing out its thematic as well as its aim in order to ascribe it to a specific iconographic corpus: we are making reference to the picture which represents the Mystic Press. This contribution just pretends to reveal how the study of this piece is possible reveal the pedagogic use by the post Trento’s Catholic Church of two of the main instruments such as the existence of Purgatory and the the Santisimo Sacramento cult as part of a determined ideology

Tau Custodian searches at the LHC

The tau lepton can be more composite than naively expected in models of strong electroweak symmetry breaking with tri-bimaximal lepton mixing. New leptonic resonances required by custodial symmetry, the tau custodians, can then be the first signal of this lepton flavor realization. Tau custodians can be very light, decaying almost exclusively into taus. The LHC reach for these new leptons is up to masses of 240, 480 and 720 GeV for sqrt{s}=14 TeV and an integrated luminosity of 30, 300 and 3000 fb^{-1}, respectively. Our analysis can be extended to any pair produced particles decaying mostly into taus and Standard Model bosons.Comment: 12 pages, 2 figure

Propiedad de Markov de los procesos localmente estacionarios

By means of the spectral decomposition of the ordinary (non-generalized) locally homogeneous fields and of a result of Kallianpur-Mandrekar, we prove the Markov property with respect to all open sets for those locally homogeneous fields with the inverse of a polinomial as its Lévy measur

The correlation of visibility noise and its impact on the radiometric resolution of an aperture synthesis radiometer

The correlation between the visibility samples' noise of an aperture synthesis radiometer are required for the computation of the recovered temperature noise of a given pixel and of the improvement introduced by baseline redundance. A general expression for this correlation and noise examples for a linear array are presented.Peer ReviewedPostprint (published version

Learning-Based Adaptation for Personalized Mobility Assistance

Mobility assistance is of key importance for people with disabilities to remain autonomous in their preferred environments. In severe cases, assistance can be provided by robotized wheelchairs that can perform complex maneuvers and/or correct the user’s commands. User’s acceptance is of key importance, as some users do not like their commands to be modified. This work presents a solution to improve acceptance. It consists of making the robot learn how the user drives so corrections will not be so noticeable to the user. Case Based Reasoning (CBR) is used to acquire a user’s driving model reactive level. Experiments with volunteers at Fondazione Santa Lucia (FSL) have proven that, indeed, this customized approach at assistance increases acceptance by the user.This work has been partially supported by the Spanish Ministerio de Educacion y Ciencia (MEC), Project TEC2011-29106-C02-01. The authors would like to thank Santa Lucia Hospedale and all volunteers for their kind cooperation and Sauer Medica for providing the power wheelchair

Una aproximación a la educación en medios en África

In this paper we make an approach to media education in Africa. The called Media Literacy is a social, academic and cultural movement, with special development in certain countries in Latin America and a wide presence in Europe and, to a lesser extent, in other countries. In 1979 Unesco expressly referred to the importance of knowing by society the implications which correspond to the media, due to the importance in many different areas of daily life of citizens. More than three decades later, the aspirations of a suitable media education are extended to the new platforms of media, with the Internet leading, and keep on being of interest as mainstay of civic participation and democratic depth. All of it, without forgetting the rightful role in all parts with respect to the communication for development and communication for social change. En este trabajo se estudia la evolución y la situación presente de la llamada Educación en Medios (Media Literacy) en el contexto internacional y en África en particular. Se trata de un movimiento social, académico y cultural con especial desarrollo en determinados países de América Latina y una amplia presencia en Europa y, en menor medida, en otros continentes. La Unesco se refirió expresamente en 1979 a la importancia de conocer por parte de la sociedad cuantas implicaciones corresponden a los medios de comunicación, por su trascendencia en los más diferentes ámbitos del día a día de los ciudadanos. Más de tres decenios después, las aspiraciones de una adecuada educación mediática se amplían a las nuevas plataformas de medios, con Internet a la cabeza, y siguen siendo motivo de interés como pilar de participación cívica y profundización democrática. Todo ello sin olvidar el papel que le corresponde en todas las latitudes respecto a la comunicación para el desarrollo y a la comunicación para el cambio social

Nanosized Calcium Phosphates as Novel Macronutrient Nano-Fertilizers

The need for qualitatively and quantitatively enhanced food production, necessary for feeding a progressively increasingWorld population, requires the adoption of new and sustainable agricultural protocols. Among them, limiting the waste of fertilizers in the environment has become a global target. Nanotechnology can offer the possibility of designing and preparing novel materials alternative to conventional fertilizers, which are more readily absorbed by plant roots and, therefore, enhance nutrient use efficiency. In this context, during the last decade, great attention has been paid to calcium phosphate nanoparticles (CaP), particularly nanocrystalline apatite and amorphous calcium phosphate, as potential macronutrient nano-fertilizers with superior nutrient-use efficiency to their conventional counterparts. Their inherent content in macronutrients, like phosphorus, and gradual solubility in water have been exploited for their use as slow P-nano-fertilizers. Likewise, their large (specific) surfaces, due to their nanometric size, have been functionalized with additional macronutrient-containing species, like urea or nitrate, to generate N-nano-fertilizers with more advantageous nitrogen-releasing profiles. In this regard, several studies report encouraging results on the superior nutrient use efficiency showed by CaP nano-fertilizers in several crops than their conventional counterparts. Based on this, the advances of this topic are reviewed here and critically discussed, with special emphasis on the preparation and characterization approaches employed to synthesize/functionalize the engineered nanoparticles, as well as on their fertilization properties in different crops and in different (soil, foliar, fertigation and hydroponic) conditions. In addition, the remaining challenges in progress toward the real application of CaP as nano-fertilizers, involving several fields (i.e., agronomic or material science sectors), are identified and discussed.Fondazione Cariplo 2016-0648University of Granada PPJIA2021.20Marie Sklodowska-Curie Individual Fellowship within the European Union H2020 programme H2020-MSCA-IF-2019-EF-ST-888972-PSustMO

Towards a Shared Control Navigation Function:Efficiency Based Command Modulation

This paper presents a novel shared control algorithm for robotized wheelchairs. The proposed algorithm is a new method to extend autonomous navigation techniques into the shared control domain. It reactively combines user’s and robot’s commands into a continuous function that approximates a classic Navigation Function (NF) by weighting input commands with NF constraints. Our approach overcomes the main drawbacks of NFs -calculus complexity and limitations on environment modeling- so it can be used in dynamic unstructured environments. It also benefits from NF properties: convergence to destination, smooth paths and safe navigation. Due to the user’s contribution to control, our function is not strictly a NF, so we call it a pseudo-navigation function (PNF) instead.Universidad de Málaga.
